If you have never checked out the COV Open Data Catalogue, it’s time to go take a look (link).
While it may be just a boring set of lists of location and scheduling data, the things that it can be made to do are very useful. Take Vantrash.ca for example (link), a service assembled in spare time by a couple of VHS guys.
Another excellent example, the Google maps which was assembled using the city’s database of their own properties. (map) Every property shown is owned by the city.
Super useful if you ever want to ask the city for a place to start a social enterprise.
